"In
pal-1(
e2091), only two cells were stained, consistent with the loss of PAL-1 expression in V6 (Fig. 3B) (Hunter et al. 1999). In
pal-1(
e2091);
sop-1(
bx92), three MAB-5-positive cells were visible (n = 4/4) (Fig. 3C). PAL-1 staining was weak and difficult to localize to individual cells, but was consistent with expression in the cell identified as V6 (Fig. 3C)."
